About the Operational Stress Injury Clinic

The Royal’s Operational Stress Injury (OSI) Clinic is part of a national network of OSI clinics funded by Veterans Affairs Canada (VAC). We provide specialized mental health services for people living with psychological injuries related to service in the Canadian Armed Forces (CAF) or the Royal Canadian Mounted Police (RCMP).

Referrals must be made through VAC, RCMP or the CAF.

What is an OSI?

An operational stress injury (OSI is a persistent psychological difficulty resulting from service-related duties. It is not a medical diagnosis. It’s a broad term that includes posttraumatic stress disorder (PTSD), anxiety disorders, depression and other challenges that affect daily functioning. OSIs may develop after trauma, grief, operational fatigue or ongoing exposure to high-stress environments.

PTSD is one of the most common OSIs. Symptoms may begin soon after a traumatic event or appear years later. They may include:

  • Intrusive thoughts, nightmares or flashbacks
  • Avoidance of reminders of the trauma
  • Emotional numbness or feeling disconnected
  • Hypervigilance or exaggerated startle response

While short-term distress is common after trauma, persistent symptoms may require treatment. Early intervention can improve recovery.

OSI Connect

OSI Connect is a free mental health and self-management app developed by The Royal and VAC to build understanding of OSIs and connect people to the OSI Clinic Network. The app has self-assessments, recovery stories, self-care strategies and resources for healthcare providers and families.

Resource for Caregivers

We have collaborated with VAC and Military Family Services to create a set of educational and self-care tools for those supporting someone with an operational stress injury. This resource page is intended to provide OSI education and self-care tools to support individuals in a caregiver role.
